Menchi possesses a unique method of fighting: after research on pheromones for years, Menchi has developed certain fragrances that she can release as perfume to the air, and forces her opponents to inhale it. Each fragrance has different effects over the organism of her targets. To this style, she refers as Battle Fragrances (戦いの香り (バトルフレグランス),Batoru Fureguransu?).
The pheromones may even increase stamina, slightly stimulate the healing process (similar to hormones secreted by Emporio Ivankov's Horu Horu no Mi) or, when utilized offensively, cause foes to become disoriented, violent or extremely sick. One can issue a gas that makes people who inhale it poisoned or even activate an allergic reaction. The victims are still in control of their conscious, but have a weakened disciple.
